Thermodynamic properties calculator for fluids and refrigerants

Thermoprops is a free online calculator powered by CoolProp. Pick a fluid, fix two independent properties and get the full thermodynamic state: temperature, pressure, density, enthalpy, entropy, internal energy, quality and more.

• 30 common fluids and refrigerants: water, air, ammonia, CO₂, nitrogen, R134a, R410A, R32, R1234yf, propane…
• SI and imperial units, with temperature in °C, K or °F.
• p–h, T–s, h–s, p–v, T–v and p–T diagrams with saturation curves, isolines and all your states plotted together.
• Shareable links that keep your fluid, units and states.
